NUN-SMDING DEVICE FOR VEBIGLE-WHEELS.

To all whom t may concern:

Be it known that l, Dommel; Crnmoo, a citizen of the United States, and a resident of Yonkers. in the county of Westchester and State of New Yorlnhave invented certain new and useful Improvements in Non-Skid ding Devices for Vehicle-Wheels, of which the followingl is a specioation.

'lhe invention pertains more particularly to transverse anti-skid devices or chains apother shdding of on slippery or other survehicle wheels to prevent the the wheels when faces..

rlhere have been many forms ot anti-skid chains devised, but a demand exists for one which may be more ecient than vthe others and probably not as expensive. l'lhe object of my invention is to provide a thoroughly ecient set of anti-skid devices or chains to be applied transversely upon the tires oi automobile wheels and which may he produced at reasonable is tc provide anti-skid chains of the class referred to which Ywill avoid injury to the tire.

The transverse anti-skid device or chain of my invention is composed of links hing- Y edly connected together and has at its ends suitable pivoted hooks by which the device or chain may be connected with the means by which the same is secured to the wheel. 'llhe links constituting the body ofthe chain or my invention are of special formation and each is in one individual piece and the adjoining links oi' the chain are freely connected together by small loops, the whole presenting a chain whose inner `surface which engages the tire is broad and flat and whose outer surface has on each operative link a series ci road, there preferably being not less than ve of these projections so d1sposed that two are at each side of each ot said links andV one at about the transverse center of the link. 'lhe links intermediate their ends and central transverse portion are open, thus leaving at the ends of the link transverse crosshars adapted to receive the loops hy which the links are connected together.

chain composed of the links of my invention v is not only efficient and capable of being readily manufactured at reasonable expense, but is one of great strength and durability and capable of withstanding rough treatment. Y

The invention will be fully understood from the detailed description hereinafter presented,ret'erence being` had to the accompanyingV drawings, in which:

Figure l is a side elevation of an antiskid device embodying my invention;

Fig. 2 is a top view of the same extended outwardly to lie at;

Fig'. 3 is a longitudinal sectionthrough two links of the device or chain and shows `the loops, partly broken away for connect ing` the links together;

Fig'. d is a side view of a portion 'of the tire oi' a wheel havingr applied thereto the anti-skid chains of my invention, these transverse anti-skid chains being in this instance connected at their ends with chains which extend around the wheel-adjacent to the inner portion of the tire;

Fig. 5 is a transversesection through a portion of a wheel having the transverse anti-skid chain of my invention applied thereto, said chain being'` shown as secured to the wheel 'by means of a clamp applied to a spoke thereof and to which .clamp the ends of the chain are connected;

Fig. 6 is a side elevation of the same;

Fig. 7 is a detached top view of one link oi my mansverse anti-skid chain, this link being' modified in form from the construction of link shown in Figs. l, 2 and 3;

Fig. 8 isY a vertical section through the same taken on the dotted line 8-8 of Fig. 7,

Yand

Fig.. 9 is a horizontal section through the spoke shown in Figs and 6, and illustrates the clamp by which the anti-skid chain is secured upon the wheel, the'section being on the dotted line 9-,9 of Fig. 6.

In the drawings, l0 designates a. portion of the tire of an automobile wheel, 11 the spokes of said wheel and l2 the anti-skid devices or chains .of my invention to be transversely applied upon the tire 10 and secured at their ends to means carried by the wheel for connecting the chains thereto. One of the transverse chains 12 is shown in Figs. i and 2 and two of these chains are and 3, denotes illustrated in Fig. 4, wherein I illustrate the wheel as having a chain 13 extending along each side thereof with the anti-skid chains of my invention connected therewith. In Figs. 5 and 6 I illustrate one of the transverse chains of my invention as secured upon the wheel by means of a clamp 14, which spoke 11.

Referring more the individual operative links of the chain, and 16 the loops .Which pivotally connect adjacentlinks 15 together. 'Ihe links 15 correspond with one another, and the end links, which I number 17, 'correspond with each other and have extensions 18 thereon for the formation of eyes 19 to receivethe securing hooks 20. Each of the hooks 20 is formed fromY a rod folded at about its center so as to form two members 21, whose outer ends are reversely bent, as at 22, to form hook members. v

The links 15 are each in one integral cast metal piece and comprise side members 23,

a central transverse member 24 and endl transverse bars 25. The links between their central portion 24 and transverse bars 25 are open. The transverse lbars 25 are slightly above the inner or bottom surface of the link, and the pairs of adjoining links receive the loops 16, which are plain' flat-metal loops extending between the side members 23 of the links, as shown more clearly in Fig. 2. The side members 23 of each link 15 are, at their end portion's,jinclined, as at 26, and said sides between their end portions are recessed inwardly on converging lines, as at 27, thereby leaving at eachend of each side of the link a projection 28 for engagement with the road bed, and which projections have inclined'end surfaces, as shown. The side surfaces of the side members 23 extend outwardly on converging lines, their opposite side surfaces being beveled outwardly,

as at 29 (Fig. 2)',l and this results in the projections 28 having beveled side surfaces, as well as 'beveled end edges.

'The transverse member or bar 24 of each link 15 is integral at its ends with the side members 23, and said member or bar 24 may be of the construction shown in Figs. 1 and 2 or that illustrated in Figs. 7 and 8. InA

the construction shown in Figs. 1, 2 and 3 the bar member at its central lower portion is flat, and upon this flat portion there is an outwardly projecting section whichin this instance, is formed of twoV-flanges 30,

which extend inwardly from the corners to the central pprtion of the member or bar 24 and prefera versely of the link and rising from the fiat is detachably fastened upon the` particularly to Figs. 1 2

'37 and therewith prevent the screws ly, though not necessarily, are separated from each other at the converging- Vof the members defining the X-shape are preferably beveled outwardly. The recesses 27 in the side members 23 are in line with the space between the ends of the flanges 30. The flanges 30 form a central projection or contact for coperation with the projections 28 in engaging the road-bed. l

rEhe clamp 14 shown in Figs. 5, 6 and 9, comprises two substantially corresponding sections 32, l33 adapted to fit upon opposite sides of the spoke 11 andhaving at their opposite side ledges slotted facing lips 34, 35. Screws 36 are hinged on the lips`34 and may be swung intok the slots of the lips 35, and then by means of nuts 37 on said screws the two sections of the clamp may be rmly bound on the spoke 11. rIhe lips 35 my have outwardly turned outer edges to be engaged by the side of the lnuts 36 from being jarred from their connection `with said lips 35 during the travel. of the vehicle. The clamp sections 32, 33 have outwardly diverging arms 38 carrying'pivoted links 39, which are open loops and receive the hook members on-the ends of the chain 12. The clamp sections 32, 33 may have a lining 40 of felt or the like to prevent marrng of the spoke 11 by the-clamp. v

The link shown in Figs. 7 and 8 is numbered 41 and may be employedin the chains 12 as a substitute for the links 15 therein.

' 'Ihe link 41 differs from the link 15 mainly in the form of the central cross-bar member, which in Figs. 7 and 8 is numbered 42. The member 42 has a transverse projectm rib or contact 43, which tapersI downwar y and outwardly at its ends and is spaced from the side members of the link. The contact projection 43 is in line with the recesses 44 in the side members of the link, and said side members afford end contact projections 45. vThe link 41 is open between its central cross-bar and its ends and at said ends are the crossbars 46 to receive the flat metal connecting loops 16.

` The transverse chains may be made up of the links 15 or the links 41, as may be preferred.v I think possibly the link 41 may be more compactly and durably .constructed than' the link 15 ibut both forms of links are desirable.' The broad flat connecting loo s 16 are very ellicient and present, as do tlie links, broad flat surfaces to the tire.
